A low cost high performance SPWM inverter

Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems. PEDS'99 (Cat. No.99TH8475), 1999
Sine wave pulse width modulation is most widely used in three-phase motor drives, UPS systems, static VAr compensators, etc. Variable frequency sine wave outputs with high stability can be achieved with digital circuits employing EPROMs and DACs.

FPGA-implemented carrier based SPWM multilevel controller

2004 IEEE Africon. 7th Africon Conference in Africa (IEEE Cat. No.04CH37590), 2005
Multilevel converters were originally developed for high voltage high current applications. These topologies have several advantages to offer that include voltage blocking requirements for the individual components in the switch matrix, lower EMI generation, lower THD, better output waveform as well as higher efficiency for a given quality of output ...

FPGA implementation of configurable three-Phase SPWM module

CCCA12, 2012
The work presented in this note concerns designing and implementation of a three phase SPWM reconfigurable module for power inverters to drive induction machines. In this paper we emphasise on reconfigurabilty of the SPWM characteristics such as modulation index, carrier frequency, modulating signal frequency and dead-time.

Repetitive waveform correction technique for CVCF-SPWM inverters

2000 IEEE 31st Annual Power Electronics Specialists Conference. Conference Proceedings (Cat. No.00CH37018), 2002
A way to synthesize a repetitive controller directly with SPWM inverters is presented. It combines the advantages of repetitive control (low THD with nonlinear loads) and SPWM technique (easy implementation, low cost, reliable operation, etc). To cancel out the high resonant peak of the SPWM inverter, the repetitive controller incorporates a notch ...

Modeling of FACTS Devices Based on SPWM VSCs

IEEE Transactions on Power Delivery, 2009
In this contribution, two voltage-source converter (VSC) models based on Fourier series and hyperbolic tangent function are proposed. The models are described in detail. The proposed models can be used for fast simulation in the time domain of power-electronic devices based on sinusoidal pulse-width modulation VSCs; the undesirable error introduced by ...
